CARPET-SWEEPER.

SPECIFICATION forming vpart of Letters Patent No. 259,069, dated June 6,1882.

Application Inca January *1, 1882. (Model.)

To all whom 'it may concern Be it known that I, HENRY S. WING, ofAshtabula, in the county of Ashtabula and State of Ohio, have inventedcertain new and useful Improvements in Garpet-Sweepers; and I do hereby4declare the followingto be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to an improvement in 'carpet-sweepers, the objectbeing to simplify and improve the construction and operation of thesedevices, and to provide a sweeper of such construction that it may bemanufactured. at small cost and be durable in use.

With these ends in view the invention consists in combining with the endpieces and pans of a carpet-sweeper a slotted bell-crank lever fordumping said pans.

The invention further consists in the combination, with thefriction-rollers and brush of a sweeper, of devices of the improvedconstruction' hereinafter described for supporting and adjusting saidbrush.

The invention further consists in the parts and combinations of parts,hereinafter fully described, whereby the pans of the sweepermay betilted or dumped and forced back in operative position by the weight andpressure ap-l plied to the sweeper.

The invention further consists of the details of constructionhereinafter fully described, and pointed out in the claims.

In the accompanyingdrawings, Figurel represents a perspective view ofasweeper constructed in accordance with my invention. Fig. '2 is acentral vertical section of Fig. 1. Figs. 3 and 4 represent parts indetail.` Fig. 5 is a longitudinal section, and Fig. 6 is a modication.end of the sweeper to illustrate. the stud or journal projecting fromthe pan. .Y

A represents the casing ot' the sweeper, having end pieces,.B B, betweenwhich are pivoted the tilting pans C by pivots' c. These pansvare eachconstructed at one end with an inwardly-projecting ear or arm, c', eachprovid'edwith an inwardly projecting stud, c2 and c3.

following-described means. brush-roller is provided with a stud, h,while lthe opposite end has an annular recess, h', a

D represents a bell-crank lever, pivoted to the inner side'of the end Bofthe casing by a pivot, b. The lower end of this lever is formed with adiagonal slot, b', adapted to receive the stud c2 of the pan C. Ahorizontal slot, b2, is

formed inthe opposite end of the lower arm of the lever to receive thestud c3 ot' the other pan, G. The upper end of the lever projectsthrough a slot, not the casing, and is adapted to register with notchese formed in the end ot' the top brace, E, of the casing. The under sidesofthe pans C, at the ends adjacent to the piece B, are provided eachwith a runner, f, secured tothe bottom and side of the pan. The oppositeends of the pans C are each provided with a flange, f', through thelower end` of which passes la pivot, f2, securing the pan to the endpiece B of the casing. The latter is provided with a central verticalslot, b2, and on each side with a diagonal slot, b3. Astud, b4, projectsfrom the outer side of each of the anges f of the pans, and extendsthrough the diagonal slots b3 of the end piecev B', and

upon these studs are mounted friction-wheels.

Gr G, one on each side of the central slot, b, of the end piece B'.

It will vbe Vobserved that by the construction thusfar described the twopans C C may be readily tilted or dumped by means ofthe bellcrank' leverD; also, it will be clear that when said pans aredumped in oppositedirections:

by means of the bell-crank lever the friction-v wheels, which arejournaled upon studs of the pans, said studs projecting through thediagonal slots of the end piece B', will be carried lwith the pans inopposite directions, and after the dust in the pans has been removed thelat- Qter may be quickly restored to their operative ,position bystriking them upon the floor. Fig. 7 is a section taken through oneHrepresents the brush, ofthe usual circular orroller form, secured inposition by the friction-wheel, h2, anda central pivot or stud, h3,projecting from the latter. I `represents a bell-crank lever, pivoted tothe inner side of` the end piece B of the cas-v ing by a pivot, fi. Theinner end of this lever One end ot' the is provided with a bearing, i',adapted to receive the stud h of the brush-roller. The upper end of thelever I projects through a slot, i2, of the casing and registers with anotched plate, i3, secured to one side of the slot t2.

J represent a bracket having its horizontal portion 7' secured rigidlyto the under side of the adjacent end of the overhan gin g top brace, E.The depending portion j of the braeketis provided withanupperandalowerslot,lettered lfand j respectively, which are adapted toreceive studs from a sliding piece, J The latter is also guided betweenstudsj, extending from the inner side of the bracket, and is providednear its lower witha bearing, ji, adapted to receive the stud h3 of thebrush-roller.

A horizontally-sliding plate or finger-piece, K, is interposed betweenthe bracket and the bearing-piece J. It is provided with a diagonalslot, K', and is held by means of a headed stud or rivet, K2, whichpasses through the slot K and the slotj2 of the bracket. By thisconstruction the friction-wheel h2 of the brush is held between thewheels or rollers G G, with which it has frictional contact when thedevice is in operation. It will be observed that the brush-roller may beadjusted vertically by means of the lever I at one end, and by thesliding finger-piece and its connections at the opposite end. v

L represents a handle-socket provided with arms Z, the ends of thelatter being bent outwardly and secured pivotally in bearings M, securedby screws m to the casing. An elastic washer, m', surrounds the ends ofthe arms l withinthebearings M. A catch, N, preferably of spring metal,is secured to the top brace at about the center of the latter, andadjacent to the handle-socket L. A rigid brace or bracket, n, secured tothe casing below said catch, and to the under side of the latter, servesto support and give rigidity to the catch. By this construction thesocket L is adapted to be turned over the catch and securely held, thenecessarysprin g action or yielding of the parts being secured by theuse of the elastic washers m.

Instead of making the catch N and brace or brackets a of two separatepieces, as above described, they can be made of a single piece of metaland answer all the necessary purposes.

In Fig. 5 is represented a modification of the end piece B. In thisfigure the diagonal slots b3 of the end piece B are avoided and thecorners of the piece are cut away, and the ends m2 m2 of the pans formpart of the end piece, and to these ends m2 m2 the friction-wheels G Gmay be secured by studs,as represented in the other figures.

By the construction and arrangement herein described I am enabled todispense entirely with casin gs for the friction devices, and moreoverproduce a friction device of few and simple parts, easilyoperated, anddurable and reliablein use.

It will be apparent that I may make many slight alterations in thedetails of construction of my improved sweeper without departing fromthe spiritof my invention. HenceI would have it understood that I do notlimit myself to the exact construction shown and described, but reserveto myself the right to make all such changes of form and construction asmay properly fall within the scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
